This image was created for use with dogestry. We wanted a caching HTTP proxy between our servers and S3 so that images were only downloaded once from S3.
The image assumes a config file in the container at: /nginx.conf so use the -v option to
mount one from your host.
docker run -p 8000:8000 -v /path/to/nginx.conf:/nginx.conf coopernurse/nginx-s3-proxy
If you want to store the cache on the host, bind a path to /data/cache:
docker run -p 8000:8000 -v /path/to/nginx.conf:/nginx.conf -v /my/path:/data/cache coopernurse/nginx-s3-proxy
Feel free to alter the -p param if you wish to bind the port differently onto the host.
Example nginx.conf file:
worker_processes 2;
pid /run/nginx.pid;
daemon off;
events {
worker_connections 768;
}
http {
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
server_names_hash_bucket_size 64;
include /usr/local/nginx/conf/mime.types;
default_type application/octet-stream;
access_log /usr/local/nginx/logs/access.log;
error_log /usr/local/nginx/logs/error.log;
gzip on;
gzip_disable "msie6";
gzip_http_version 1.1;
gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
proxy_cache_lock on;
proxy_cache_lock_timeout 60s;
proxy_cache_path /data/cache levels=1:2 keys_zone=s3cache:10m max_size=30g;
server {
listen 8000;
location / {
proxy_pass https://your-bucket.s3.amazonaws.com;
aws_access_key your-access-key;
aws_secret_key your-secret-key;
s3_bucket your-bucket;
proxy_set_header Authorization $s3_auth_token;
proxy_set_header x-amz-date $aws_date;
proxy_cache s3cache;
proxy_cache_valid 200 302 24h;
}
}
}
Things you want to tweak include:
- proxy_cache_path
- alter max_size as desired
- if you want the cache stored external to the container, alter the path
- proxy_pass
- aws_access_key
- aws_secret_key
- s3_bucket
- proxy_cache_valid - change 24h to your cache duration as desired.
